Are compression fittings as good as solder?
Compression fittings are not nearly as robust as soldered fittings making them much more sensitive to powerful stresses. They are not ideal for applications where they could be potentially exposed to lots of flexing, bending and excessive vibration or tube movement.
How much pressure can copper compression fittings hold?
The fittings used are compression or flare type threaded fittings. The copper in annealed pipe is softer than the copper in drawn pipe and withstands less pressure. Type M, 3/4-inch drawn copper pipe handles a maximum of 701 pounds per square inch at 100 degrees.

How do I stop my compression fitting from leaking?
Tighten compression fittings firmly with two wrenches to crimp the ferrule onto the pipe (Photo 3). Also make sure the pipe or tube goes straight into the fitting. Misalignment will cause a leak. If the fitting leaks after you turn on the water, try tightening the nut an additional one-quarter turn.
Do compression fittings need gaskets?
Unlike other types of joints, compression fittings do not need additional sealing materials like gaskets or o-rings because they seal through the use of threads alone.
Should you use Teflon tape on a compression fitting?
Also, do not use too much Teflon tape as this could be counterproductive and prevent the joint from sealing properly and/or causing the tape to gum up. DO NOT use Teflon tape under the compression nut or on flare threads of brass compression fittings (or a compression fitting of any other material)!
Do you use sealant on compression fittings?
"Should I use PTFE thread sealing tape or pipe joint compound on my compression threads?" A. No, you definitely should not.

What is a copper pressure fitting?
Copper press fitting is a flameless alternative to soldering copper pipe connections. In this system, a hydraulic tool is used to press specially designed connectors to join traditional pipes. These connectors house a sealing element that, when pressed, creates an even and reliable connection.
How much pressure can a soldered copper pipe hold?
A soldered four-inch Type L joint has a pressure rating of 440 psi. If the plumber in the field decides to braze that joint rather than solder it, the rating will be reduced to 293 psi — the annealed rating.
How to join copper pipe?
Step 1. Prepping the pipe. As with any kind of pipe join, before you start, clean the pipe with a special copper pipe cleaner or simply use wire wool. This will remove a lot of the grime and dirt from the pipe and ensure a better join. Although, for compression joins this is less important than for solder joins. Step 2. Taping the end of the pipe.
How to tighten a pipe nut?
Then do the same with the nut. Hand tighten as much as possible. Step 5. Tighten with a spanner. Use your adjustable spanner to get a good grip on the join nut. Tighten as much as possible to ensure a good leak-proof join.
How to seal a pipe with PTFE tape?
Take your PTFE tape and wrap it around the end of the pipe that’s forming the join. A couple of complete turns of the tape should be enough to help form a tighter seal.
What happens if you crush a pipe?
If you crush the pipe, then you must replace it.
How to install a compression fitting on a pipe?
Slip the compression nut from the compression fitting onto the pipe, then slip on the compression ring. Slide both pieces down so they are 1 inch or so from the end of the pipe. Fit the compression fitting onto the pipe (or fit the pipe into the fitting, as applicable) until the pipe stops inside the fitting.
What is compression fitting?
A compression fitting is not a specific plumbing part but rather a type of fastening system for valves, water supply tubes and other plumbing fittings. The valve (or other part) has a port where the pipe slips in, and the port has male threads on the outside. Before you fit the parts together, you slide a compression nut ...
How to check if a compression fitting is leaking?
Check the compression fitting for leaks after you've completed all of the other plumbing connections and turned on the water supply to the pipe. If the compression fitting leaks, use both wrenches to tighten the compression nut gently until the leak stops.
How to cut a pipe?
Cut the end of the pipe, if necessary, using a tubing cutter. Open the jaws of the tubing cutter and fit it onto the pipe so the pipe rests squarely against the two flat rollers of the cutter. Tighten the cutter so the cutting wheel is snug against the pipe.
How to seal a pipe with a nut?
Once the pipe and fitting are together, you slide the ring against the fitting, then thread the nut onto the fitting. The nut compresses the ring between itself and the fitting, and the tapered edges of the ring are wedged tight inside the fitting and the nut, creating a watertight seal.
How to tighten compression nut?
Slide the nut over the ring and thread it onto the fitting until it is hand-tight. Be careful not to cross-thread the nut. Fit one wrench onto the body of the fitting and hold it so that the fitting doesn't move. Use another wrench to tighten the compression nut about one-half to three-quarters of a turn.
How to clean a pipe smooth?
Clean the outside of the pipe with a rag; it must be clean, with no paint or other contaminants. If necessary, apply a cleaner or solvent to the rag to clean the pipe .
Why are compression fittings so popular?
Compression fittings are ingenious because you can use them in places where welding isn’t an option.
How to tighten a retainer nut?
To ensure that the fitting is properly seated, what I like to do is tighten it ever so slightly, then hit the back of the fitting to ensure it’s seated properly, as opposed to hitting it without tightening it, it would bounce back and not seat properly. Once that’s done, go ahead and start tightening it. Your cue for knowing when they are tight enough is when you start to hear a squeaking noise as you are tightening, this is caused by the rotational friction between all the parts inside.
How Does a Compression Fitting Work?
Okay, time to get into the nitty gritty of compression fittings. But first, we need to explain how a compression fitting works. While reading this, take a look at the diagram below. It will help you visualize how everything’s put together.
How to tighten a pipe?
Tighten Each Side. Place one crescent wrench on the union. Use your second crescent wrench to tighten each side ( the first wrench is used to keep the pipe stable while you’re tightening with the second wrench). Once snug, tighten about one more half turn.
How to fix a leaky tubing?
Tighten the compression nut with a wrench, forcing the ferrule down into the tubing to secure and seal the connection. If the joint leaks when the water is turned on, tighten the nut a quarter turn at a time until the leak stops. Don’t over-tighten the joint. Too much pressure can crush the tubing or crack the nut.
What is ferrule in plumbing?
A ferrule is a metal band that forms or strengthens a joint. Because copper is a soft metal, the seal can be extremely tight. Use pipe joint compound (or Teflon plumber’s tape) to make sure the seal is watertight. You should also anchor or support the tubing within two feet of either side of the fitting. A side-view showing how the compression nut ...
Why use compression fittings?
You’ll want to use compression fittings in a situation where the run of pipe needs to be taken apart or when an area of the pipe will be difficult to solder. One common location in which this occurs is on supply lines to a bathroom, laundry, or kitchen sink because they have compression fittings at both the stop valve and the faucet inlet.
What happens if you don't bend a pipe?
If you don’t bend the pipe in a gradual, sweeping arc, you’ll be surprised how fast it will kink. And a kink in the pipe is nearly impossible to get back to the right shape. You’ll need to throw the piece away.
How to join a compression joint?
If you don’t need to create a compression joint, but rather need to join a compression union, then follow these steps. 1. Shut Off the Water. I know, it gets annoying having to read this same instruction over and over. But really, it’s that important.
